Smoke Alarms Set Up Issue

I had Ring alarm installed today, and the installation included 3 battery-operated First Alert Smoke / CO detectors. The 3 detectors are visible and seem to be functioning correctly. They have new unique names. However, in my Alarm Devices list, 6 detectors are showing up: the 3 that I installed with their new unique names, and 3 more that have the generic names and if I click in to each of them they still have the "Finish Setup" option. If for these devices I go into the settings and attempt to "Remove" it tells me that I need to remove the batteries. I cannot do this b/c they are essentially phantom devices. Can I remove each of these 3 by going into "Advanced Settings" for each device and choosed "Remove Failed Device"? I am just trying to prevent the 3 working detectors from being removed and requiring new installation. See screenshot. Thanks!
